They do it in the UK with Sky.
And I discovered they do it here with Metz
a German manufacturer, who filed for bankruptcy in January 2015, but still appears to be in business. They have built-in Cablecom reciever and HD recorder - and good sounding speaker.
The downside is they are not cheap. Anyone know of any other TVs with built-in Cablecom receiver/recorder - and good sound system all in one? I'm trying top be tidy...
